Is OSB board water resistant?
As a general rule, most OSB are water resistant. Due to their construction process using wood strands, resins and wax they come fairly water resistant.
However, if you're looking for a truly waterproof OSB you need to make sure it is stamped stating so.
How do you seal OSB?
Soak the tip of your paintbrush in your sealer and begin brushing it over the surface and on the ends of the OSB pieces.
Make sure you repeat this process on each side, not just where your cuts were made. Coat the pieces as they lay on the tarp, and then let the waterproofing sit to dry for 12 to 14 hours
